Abstract

We report the synthesis of a novel isotope engineered

¹³C-

¹²C heteronuclear nanostructure: single-wall carbon nanotubes made of

¹³C enriched clusters which are embedded in natural carbon regions. The material is synthesized with a high temperature annealing from

¹³C enriched benzene and natural C

₆₀, which are coencapsulated inside host SWCNTs in an alternating fashion. The Raman 2D line indicates that the

¹³C isotopes are not distributed uniformly in the inner tubes. A semiempirical method based modeling of the Raman modes under

¹³C isotope enrichment shows that experimental data is compatible with the presence of

¹³C rich clusters which are embedded in a natural carbon containing matrix.
